XP or Vista?

I don't know much about Pc gaming, but I've finally decided that by mid-January I will be buying one. My friend made me a computer (specs will be at bottum of post) and also bought me Crysis yesterday for my birthday. I decided to look in on the game and dropped into the forums. After reading alot of posts, I found alot of people saying the game runs alot better on XP then Vista.

So my question is which OS should I buy, Vista or XP?

I think Vista looks great. My friend already using that (Vista Home Edition) But as for me, I'm not fully convince about the capabilities of Vista. Its not that is isn't good, since I still have some old softwares that could only at least run at XP, so tha's why I'm not yet giving up to my XP...

But since you're PC has a great specs, I think its not bad to try Vista. But make sure all of your programs can run through Vista...

....I can't find the edit key on this forum.....

Moreover NVIDIA & MS are still working hard on fixing Vista game performance, but if Vista will overtake WinXP performance anytime soon is anybodies guess.

XP for now

Vista after they fix those 1 million bugs. Most games don't work or have problems on Vista

Just go with Vista there is no reason why you shouldnt, as much as people would like to think otherwise Vista is the future, people bash vista saying that no games work on it or they have performance problems, well think back to when XP was first released it was terrible, Vista is alot more stable than XP was when it was first released.

Vista isfine at the momentand its only going to get better, plus it looks oh so very sexy.

For now and having an easier time XP is smarter as vista has some bugs that can be aggrovating to Gamers. I have Vista & XP and I am currently on XP. I have Tried Vista Twice now and have had to change back because of the performance of the Games I currently play just presents problems in vista, constant crashes are the worst part.

2nd just advice. SLI is atotal waste of time & Money. Just get 1 8800 GTX. SLI will never become a standard anytime soon too many designers and publishers just ignore it, for the time being at least. your smarter to get 1 video card. Youll have the ability to SLI because of your motherboard in the future but DONT WASTE YOUR MONEY YET on a technology barely any games actually take advantage of. I can run anygame right now on max settings at 1920 x 1200 with my 1 8800GTX and your setup is just a hair better than mine.
